Shaft Coupler Hub L150 7/8 in Bore

The Dayton 29HY49 is a sintered iron jaw coupling hub sized for L150 elements with a 7/8 inch round bore and keyway. It suits power transmission assemblies where a straight jaw profile and set screw locking are specified. Builders needing a different bore diameter or clamping style will need another hub.

Capacity and Speed Limits

Rated for 5,000 RPM maximum speed, the hub transmits 2.0 hp at 100 RPM with a Buna-N spider, 3.0 hp with a urethane spider and 5.9 hp with a Hytrel spider. Overall length is 4 1/2 inches and outside diameter is 3 3/4 inches. Applications exceeding these horsepower or speed ratings require a larger coupling size.

Compatible Center Elements

The hub accepts Dayton centre elements with part numbers L150H, L150N and L150U, letting the installer choose spider material for the required torque and damping characteristics. No other element series fits the L150 jaw profile. Software or additional accessories are not supplied with this mechanical component.

Questions about this item

Will the L150 hub with its 7/8 in bore and 3/16 in keyway fit the existing shaft on my older motor?

The hub has a 7/8 in round bore with a 3/16 in keyway width and 3/32 in depth; match those dimensions to your shaft and key stock for a proper fit.

How can I confirm the coupling is running correctly after installation?

Verify the set screws are secure on the shaft, the spider seats fully between the jaws, and the assembly rotates smoothly without vibration up to the 5,000 RPM limit.

Does the box include the spider element or must I buy the L150N, L150U or L150H separately?

Only the sintered iron hub is supplied; you must purchase a compatible Buna-N, Urethane or Hytrel spider separately.
